I hadn't occurred to me to write a review of index cards but when the automated e-mail from Staples arrived asking me to review them - I figured why not? Like I said in the "Pros" section - they're index cards. What you see is what you get. If you're expecting something else say... Post-Its - you're going to be disappointed.
In addition to all of the electronic devices I regularly use the use of 3x5 cards has a very real value in two ways: 1] the card is a central archive of pertinent data for the prospect on the card and 2] organizing the cards by the prospects geographic location helps in routing business travel sales calls
